hp 2050 prints a black "splotch" under everything black
My 2050 prints color fine, but anything solid black has a black splotch under it as wide horizontally as the black item that gets printed. I have just put a new black ink cart in the printer. Communication between the printer and pc is o.k. I have attached the test page. I printed a text article.
All text and pictures print ok but every solid black part of the print has a black splotch under it. Could it be the black cartridge. I think the printer is the problem. I have realigned the printheads and cleaned them. to no avail. The attachment is a PDF.
Thank you.
